I wouldn't put that as a hard requirement. You can end up with some
amount of hard to understand code for no benefit. Do we really need to
test for jdk 1.0, 1.1?, 1.2? How about J2ME/CLDC? Java Card? How about
J2ME/CDC without foundation profile?

Sometimes it's cleaner and easier just to state in the documentation
that it requires JDK 1.5 or higher and if someone tries to run it on an
unsupported platform that's their issue.
